Reliability and Validity of Set 1 of the Depression Adjective Check Lists With the Elderly
The reliability (internal consistency, alternate form, and test-retest) and validity (concurrent and discriminant) of the state and trait versions of Set 1 (lists A, B, C, D) of the Depression Adjective Check Lists (DACL) were studied in an elderly sample (N = 338). Reliability and validity estimates for both versions were sufficiently high so as to recommend their use in research with the elderly. Suggestions for further study are mentioned.
